To get rid of the egg smell in your dishwasher, you can try a few different methods. Here are some steps you can follow:

  1. Remove any leftover food debris from the dishwasher, including any eggshells or bits of egg that may be stuck to the dishwasher’s walls or the dishes.
  2. Wash the dishwasher with a mixture of warm water and white vinegar. Vinegar is a natural disinfectant and deodorizer, and it can help to remove any lingering egg smells.
  3. Fill a dishwasher-safe cup with white vinegar and place it on the top rack of the dishwasher. Run the dishwasher on a hot water cycle to help remove any remaining smells.
  4. After the wash cycle is complete, leave the dishwasher door open for a few hours to allow it to air out. This will help to dissipate any remaining odors.
  5. If the egg smell persists, you can try using a commercial dishwasher cleaner or deodorizer, following the instructions on the product label.

Overall, the key to getting rid of the egg smell in your dishwasher is to thoroughly clean and disinfect the appliance and to allow it to air out after washing. By following these steps, you should be able to eliminate the egg smell and keep your dishwasher fresh and clean.

What Causes a Dishwasher to Smell Like Eggs

A dishwasher can develop a smell like eggs for a few different reasons. One common cause is a build-up of food debris and grease in the dishwasher, which can begin to rot and produce a foul odor.

This can happen if the dishwasher isn’t cleaned regularly or if it isn’t used frequently enough to prevent food from drying and hardening on the dishwasher’s surfaces.

Another potential cause of a bad odor in a dishwasher is a malfunctioning or broken garbage disposal, which can allow food debris to build up in the dishwasher and create a foul smell.

Additionally, certain types of dishwasher detergent or rinse aid can produce a sulfur-like odor that can be mistaken for the smell of eggs. In any case, it’s important to clean and maintain your dishwasher regularly to prevent bad smells from developing.

5 Tips to Prevent Your Dishwasher from Smelling Like Eggs

  1. Make sure to properly load your dishwasher, taking care not to overcrowd it. Overcrowding can prevent dishes from getting clean and can lead to unpleasant odors.
  2. Run your dishwasher with a dishwasher cleaner regularly to remove any built-up food or grime that may be causing odors.
  3. Keep the door of your dishwasher open when not in use to allow for proper air circulation and to prevent odors from forming.
  4. Make sure to properly rinse off dishes before loading them into the dishwasher. Any food particles left on dishes can cause odors in the dishwasher.
  5. If your dishwasher still has an unpleasant odor, try using a solution of equal parts water and white vinegar and running it through a wash cycle. This can help to remove any lingering odors and leave your dishwasher smelling fresh.


A dishwasher can develop a smell like eggs due to a build-up of food debris and grease, malfunctioning garbage disposal, or the use of certain types of dishwasher detergent or rinse aid. Regular cleaning and maintenance can help prevent this issue.
